It’s a 14g biocube that I just finally finished setting up for now, the wennerae mantis and two gobies are in there somewhere Realized after releasing them that I should have taken pics all the sand and rock were from one of my very established10 gallons, except for three pieces of tbs premium I got yesterday with the mantis and fish! So happy to finally have caulerpa in one of my tanks can’t wait to see what else comes out of the rocks! There were some cool things during unpacking. Will keep updating this thread with pics as I change things around. Getting a heater in tomorrow for it as I’ve never done heaters in my tanks… so glad I thought to put a mirror behind it so I can check on things! (And peeled off that dumb black vinyl on that one end)
